I got a 99 GTP. There has been antifreeze showing up on top of the motor, in the front and back. What would cause this? The oil level and coolant level is good and it has a good temperature range.

how many miles ya got?

I vote its the Lower Intake Manifold Gasket (LIM) too. That's about all that can really account for coolant ontop of the motor, save for any major cracks in the TB/LIM, but that'd be extremely difficult to do.

agreed on the lim gasket btw. they're probably seeping up near your valve covers and that's where you're seeing coolant.

About 175,000 miles. Is the lim gasket a "do it yourself" project?
10-29-2011
depends. can ya turn a wrench and have any knowledge on cars? if not then id say let a mechanic to it.

Make sure you use Aluminum Gaskets........ See why below site:
